Red Dot Uniforms on U.S. 80 in Pooler sustained heavy damage following a fire that started around 5 p.m. Sunday. The source of the fire is believed to be a vehicle that was parked in the business' showroom.

A Pooler business on U.S. 80 sustained heavy damage in a fire Sunday afternoon.

Firefighters from Pooler, Garden City and the 165th Airlift Wing, based at Savannah/Hilton Head International Airport, responded to the blaze at Red Dot Uniforms around 5 p.m. Pooler firefighters remained on the scene for about four hours working to keep the smoldering structure fire under control.

According to investigators, the fire is thought to have started when a showroom vehicle inside Red Dot caught fire from some sort of mechanical malfunction, said Jay Hillis, Pooler fire chief.

"We arrived and found a lot of thick black smoke, but we were able to get it knocked down pretty quickly once we removed the vehicle," Hillis said.

The fire caused "heavy" damage on the building's east side, according to Hillis. Smoke damage was significant throughout Red Dot's facilities. Smoke spread into the adjoining Dreams & Seams alteration shop.

Red Dot supplies uniforms to fire, police and EMS workers throughout the Savannah area. In fact, the business supplied the uniforms worn by firefighters who helped fight the fire Sunday, Hillis said.

"The contents of the building are definitely smoke damaged and the (east side) of the building had heavy damage to the products and whatnot," Hillis said. "We knocked out the fire pretty quickly but we'll keep a crew there for the rest of the night just to make sure."
